Future work over the next month will include installing a temporary bridge to get equipment, material and personnel in and out of the de-watered area, as well as a cofferdam for heavy equipment access and continued de-watering of the work area.
The briefing includes photos of the project, a fish rescue and relocation summary, and an overview of work scheduled through July 16th, 2022.
Work on the Nelson Dam removal and replacement project began in August 2021. The project will improve fish passage and sediment continuity to improve habitat, increase flow conveyance to decrease flooding risks for nearby landowners, and improve water supply reliability.
